Embodiment Construction

[0030] In HEVC, the coding unit (Coding Unit) architecture is introduced as a new block architecture for encoding processing. An image is first divided into Large Coding Units (Large Coding Units, hereinafter referred to as LCUs), and each LCU is adaptively divided into CUs until a leaf coding unit (leaf coding unit) is obtained or the minimum coding unit size is reached. The CU architecture information needs to be transferred to the decoder side to restore the same CU architecture at the decoder side. In order to improve the coding efficiency related to the CU architecture used for scaling HEVC, one embodiment of the present invention allows the CU architecture of the base layer (Base Layer, hereinafter referred to as BL) to be reconstructed by the enhancement layer (Enhancement Layer, hereinafter referred to as EL). use. At the LCU level or CU level of the EL, a flag may be sent to indicate whether the CU architecture is reused by the corresponding CU of the BL. If the CU ...

Abstract

A method and apparatus for scalable video coding are disclosed, wherein the video data is configured into a Base Layer (BL) and an Enhancement Layer (EL) and wherein the EL has higher spatial resolution or better video quality than the BL. According to embodiments of the present invention, information from the base layer is exploited for coding the enhancement layer. The information coding for the enhancement layer includes CU structure, motion vector predictor (MVP) information, MVP / merge candidates, intra prediction mode, residual quadtree information, texture information, residual information, context adaptive entropy coding, Adaptive Lop Filter (ALF), Sample Adaptive Offset (SAO), and deblocking filter.
